Wired: New Browsers, Same Unwanted Ads This article from Wired News reports on current trends in spyware and adware. The author discusses how people who stopped using Internet Explorer and started using alternate browsers, such as Mozilla Firefox, to avoid advertisements and improve internet security, may find that "spyware and adware writers are also making the switch." The author argues that as Mozilla gains more users, writers of spyware and adware programs will start writing for those browsers as well. On the positive side, the aAuthor(s): Creator not set

Ozone depletion interactive lab What is the process by which CFCs destroy ozone? This informational piece, part of an interactive laboratory series for grades 8-12, explores the destruction of the ozone layer by chlorofluorocarbons. Here students view a four-step animation that shows how ultraviolet light breaks chlorine free from a CFC molecule. The chlorine then destroys an ozone molecule. Additional steps show how the process can be continuous. Copyright 2005 Eisenhower National ClearinghouseAuthor(s): University of Utah. Astrophysics Science Project I

Number line bounce (grades 6-8) This online number line game for summing numbers challenges the student to find a sequence of operations with four numbers that results in a given target number. The numbers are illustrated as bouncing balls on a number line. Each bounce can be in either a positive or negative direction. The student can use a guess-and-check approach to solving the problem or a more sophisticated strategy. After finding a correct sequence and reaching the target number on the number line, the student forms the nAuthor(s): Utah State University. National Library of Virtual

Using technology to support Limited-English-Proficient (LEP) students' learning experiences This article examines the challenges and rewards related to using technology as a tool to increase learning for limited English-proficient (LEP) students. The article is based on the belief that students' content, linguistic, and technology skills should be developed in tandem. Strategies and standards for technology use are featured along with suggestions for enhancing LEP students comfort level in content classes. Access and equity and the redefinition of teacher roles are also discussed. ImprAuthor(s): Asta Svedkauskaite,Laura Reza-Hernanadez,Mary Clif

Observe forest fires as seen from space This Earth science resource shows students how atmospheric scientists use infrared imaging to detect and locate forest fires. The introduction explains how visible-light images recorded by satellites are unable to distinguish smoke from clouds. In contrast, infrared imaging, which detects heat, can detect hot spots that indicate the location of forest fires. The resource provides two different sets of satellite pictures. Students are instructed to toggle between the visible-light and infrared imAuthor(s): TERC. Center for Earth and Space Science Education

Manipula math with Java : the sum of outer angles of a polygon This interactive applet allows users to see a visual demonstration of how the sum of exterior angles of a polygon sums to 360 degrees. Students can draw a polygon and have the applet show the exterior angles. Then users decrease the scale of the image, gradually shrinking the polygon down almost to a point, while the display of the exterior angles remains and shows how the angles merge together to cover the whole 360 degrees surrounding the minuscule polygon.

How high? : measurement (grades 6-8) With this virtual manipulative, the student investigates conservation of volume with a virtual simulation of pouring a liquid from one container to a container of the same shape, but of a different size. There are four cylinder shapes to choose from: rectangular prism, cylinder, cone, and pyramid. The left container is partially filled with liquid and the base dimensions of the two cylinders are given. The student uses a slider to estimate how high the liquid will rise when poured into the seconAuthor(s): Utah State University. National Library of Virtual
